Abstract

An air stop sheet of a piston of a cylinder, the piston is accommodated in an air compressor, and an air stop sheet is accommodated on a head of the piston. The air stop sheet includes a bending section having a positioning zone and an acting zone and configured to be a boundary line of the acting zone and the positioning zone. The acting zone backing the cylinder turns on relative to the plane of the head at an open angle θ, thus producing an air flowing space. A piston rod extends downward from the head and includes a cavity, an air conduit, a column, and a spring configured to abut against the acting zone of the air stop sheet. The air stop sheet is pushed by the spring to turn on at an open angle θ, and the air conduit and the air channel communicate with atmosphere.
